摘要：

One-dimensional La2O2S:Eu3+ nanowires(NWs) were fabricated with a simple hydrothermal method.The structures were characterized by X-ray diffraction and transmission electron microscopy(TEM).The photoluminescent properties including excitation and emission spectra were studied.The results indicated that in excitation spectra there existed charge transfer(CT) absorption of both O2-→Eu3+ and S2-→Eu3+,and f-f transitions absorption in NWs and corresponding sub-meter materials(SMs).The relative intensity of CT absorption of O2-→Eu3+ to S2-→Eu3+ in both samples clearly changed.The strong yellow and red emissions of Eu3+ ions in NWs were observed.
